SIPECIFIGATION formingpart of Letters Patent No. 642,240, dated January30, 1900.

Application led August 25, 1899. Serial No. 728,430. (No model.)

To all whom t may concern:

Be it known that 1, GEORGE MILLER MAE- sHALL, a subject ot the Queen ofGreat Britain, residing at Edinburgh, Scotland, have invented certainnew and useful Improvements in Roofs, of which the following is a fulland complete specification, such as will enable those skilled in the artto which it appertains to make and use the same.

This invention relates to roofs for buildings of various kinds andforms; and the object thereof is to provide roofs of this class composedof tiling, the roof-frames and tiling and the means for holding thetiling in place being of improved form and construction,whereby aperfectly-tight roof is produced.

The invention is fully disclosed in the following specication, of whichthe accompanying drawings form a part, in which- Figure 1 is across-section of a roof constructed according to myinvention Fig. 2, aplan view of a part of the roof-frame, showing the tiling in placethereon; Fig. 3, a section on the line 23 3 of Fig 2, and Fig. 4 adetail of a part of the construction shown in Fig. 1 on an enlargedscale.

In the drawings forming part of this speciiication the separate parts ofmy improvement are designated by the same numerals of reference in eachof the views, and in said drawings I have shown a roof-frame consistingof a horizontal member 5 and an upwardly-inclined member G,which meet atthe apex of the roof, as shown at 7, and secured to this frame arehorizontal cleats or strips S, preferably composed of metal, and anydesired numberof which may be employed, the spaces between said cleatsor strips being regulated by the width of the tilings employed.

The tilings 9 are placed on the cleats or strips S longitudinallythereof, and cross cleats or strips 10 are secured to the horizontalcleats or strips 8 over the abutting ends of the tilings 9. The tilings9 are so formed that the upper edge of each is overlapped by the loweredge of the tiling placed thereover,

as shown at 11 in Fig. 3, the said edges of said tilings being beveled,so as to permit of this operation, and the cross cleats or strips 10overlap the abutting ends of the tilings 9 and are secured to thehorizontal cleats or strips S by screws or rivets 12 or in any desiredmanner.

The apex-rail 13 is substantially T-shaped in cross-section, and thecentral web 14 thereof is between the tilings 9 of the upper rows oneach side of the roof, and the said apexrail or the top thereof ispreferably convexeconcave in cross-section, as shown in Fig. et,

and by means of this construction the roof is made perfectlyWater-tight.

It will be understood that the tilings D are cemented in place, and thecross cleats or strips 10 are also cemented to the abutting ends of thetilings.

It will thus be seen that I provide a roof which is strong and durableand also comparatively inexpensive, and it will be apparent that changesin and modications of the construction described may be made withoutdeparting from the spirit of my invention or sacrilicing :itsadvantages.

Having fully described my invention, I claim as new and desire to secureby Letters Patent- A roof composed of longitudinal strips, tilings laidlongitudinally on said strips, and the ends of which abut, the top andbottom sides or edges of which being beveled to overlap, andcross-strips secured to said horizontal strips and overlapping theabutting ends of said tilin gs, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 4th day of August,1899.

GEORGE MILLER MARSHALL.
